Background: Shigella infections remain endemic in places with poor sanitation and are a leading cause of diarrheal mortality globally, as well as a major contributor to gut enteropathy and stunting. There are currently no licensed vaccines for shigellosis but it has been estimated that an effective vaccine could avert 590,000 deaths over a 20-year period. A challenge to effective Shigella vaccine development has been the low immunogenicity and protective efficacy of candidate Shigella vaccines in infants and young children.

Normal tissue reactions vary significantly among patients receiving the same radiation treatment regimen, reflecting the multifactorial etiology of late radiation toxicity. Predicting late radiation toxicity is crucial, as it aids in the initial decision-making process regarding the treatment modalities. For patients undergoing radiotherapy, anticipating late toxicity allows for planning adjustments to optimize individualized care.

Department of Public Health, Erasmus MC, University Medical Center Rotterdam, Rotterdam, the Netherlands.
Background: Specialist palliative care teams (SPCTs) have significant benefits for patients with advanced disease or frailty, including improved quality of life, greater satisfaction with care, and less potentially inappropriate care at the end of life. Experienced SPCTs are recognised to have higher referral rates compared to novice teams. The aim of this study was to assess the development of hospital-wide integration of specialist palliative care (PC) and of SPCTs in Dutch hospitals between 2014 and 2020.

Smoking is highly prevalent and persistent among people with mental illness, but implementation of smoking cessation care by mental healthcare professionals (MHCPs) is lagging behind. This study took a broad approach to understanding implementation of stop smoking support (SSS) by MHCPs (N = 220 for main analyses), incorporating background characteristics, psychosocial factors, client factors, and organizational/environmental factors. Variable selection was based on previous work and the Consolidated Framework for Implementation Research.

The needs of youth at-risk and their families, facing multiple problems and serious mental health issues, exceed the expertise and possibilities of a single stakeholder (professional, organization, municipality). These youngsters require care in which the expertise of different professionals and organizations is integrated. However, combining various types of expertise to provide integrated care to youth at-risk is challenging.

Introduction: Pain from the cervical facet joints, either due to degenerative conditions or due to whiplash-related trauma, is very common in the general population. Here, we provide an overview of the literature on the diagnosis and treatment of cervical facet-related pain with special emphasis on interventional treatment techniques.
Methods: A literature search on the diagnosis and treatment of cervical facet joint pain and whiplash-associated disorders (WAD) was performed using PubMed, Cochrane, and Embase databases.
Background And Aims: In the current study, we aimed to identify the association between major and minor electrocardiographic abnormalities and cardiovascular risk factors.
Methods: We used the Tehran cohort study baseline data, an ongoing multidisciplinary, longitudinal study designed to identify cardiovascular disease risk factors in the adult population of Tehran. The electrocardiograms (ECGs) of 7630 Iranian adults aged 35 years and above were analyzed.

Objective: Metastatic castration-resistant prostate cancer (mCRPC) is a heterogeneous disease with varying survival outcomes. This study investigated whether baseline PSMA PET/CT parameters are associated with survival and treatment response.
Methods: Sixty mCRPC patients underwent [F]PSMA-1007 PET/CT before treatment with androgen receptor-targeted agents (ARTAs) or chemotherapy.

The increasing use of recreational nitrous oxide ([Formula: see text]O) in the Netherlands and its link to traffic accidents highlights the need for reliable detection methods for law enforcement. This study focused on ex vivo detection of [Formula: see text]O in exhaled breath and examining its persistence in the human body. Firstly, a low-cost portable infrared based detector was selected and validated to detect [Formula: see text]O in air.

Myocardial infarction (MI) causes the loss of millions of cardiomyocytes, and current treatments do not address this root issue. New therapies focus on stimulating cardiomyocyte division in the adult heart, inspired by the regenerative capacities of lower vertebrates and neonatal mice. This review explores strategies for heart regeneration, offers insights into cardiomyocyte proliferation, evaluates in vivo models, and discusses integrating in vitro human cardiac models to advance cardiac regeneration research.

Purpose: To develop an improved post-processing pipeline for noise-robust accelerated phase-cycled Cartesian Single (SQ) and Triple Quantum (TQ) sodium (Na) Magnetic Resonance Imaging (MRI) of in vivo human brain at 7 T.
Theory And Methods: Our pipeline aims to tackle the challenges of Na Multi-Quantum Coherences (MQC) MRI including low Signal-to-Noise Ratio (SNR) and time-consuming Radiofrequency (RF) phase-cycling. Our method combines low-rank k-space denoising for SNR enhancement with Dynamic Mode Decomposition (DMD) to robustly separate SQ and TQ signal components.

Background: Coronary microvascular disease (CMD) is defined as impaired coronary flow reserve (CFR) and/or increased microvascular resistance (MR) without significant epicardial coronary stenosis. This definition allows for discordant CFR and MR values within patients with CMD. The aim of this meta-analysis is to characterise the prognostic value and pathophysiological backgrounds of CFR and MR con-/discordance.

The () gene family is of rising importance as their fusions are oncogenic, and specific target drugs are available to inhibit the chimera proteins. Pan-TRK antibody, which shows the overexpression of the genes, is a useful tool to detect tumors with or without gene alterations, due to high negative predictive value. Though it is well known that pan-TRK immunopositivity is usually not connected to fusion, the role of other possible genetic alterations is under-researched.
